摘　　要：报道了产于我国云南红河流域山柚子科的一个原始新属———甜菜树属 ,该属具大型圆锥花序 ,两性 ,是Lepionurus,Melientha和Champereia 3个单型属的祖型 ,无疑起源于康滇古陆即今之云南高原 ,其发现对研究山柚子科的起源与分化具重要意义。A new genus of Opiliaceae, Yunnanopilia is described from the Red River Valley, South - Central Yunnan Plateau, China. This genus is a primitive one in the Opiliaceae by having hermaphrodite flowers in large panicles, and may be the ancestry type of both Lepionurus, Melientha and Champereia . It seems that this genus may be originated in the Kam-Yunnania Ancient Landmass. This indicates that the Opiliaceae may also be orginated in the Kam-Yunnania.
